A great photo can really add a lot of flavor to a blog post and in our own analysis at Online Marketing Blog as well as with clients, including quality images with a blog post can boost traffic and referrals 30-50%. To make posts more personal, I try to use my own photos as much as possible and do use imags from Flickr under Creative Commons from time to time. This is an area of significant impact for blogs as effective communication and marketing tools, so last week we ran a Reader Poll on the best site for royalty free, stock photos for bloggers.

We had the most comments from iStockphoto users and interestingly enough, the “Other” category came in second place with suggestions including: screenshots, stock.xchng, PhotoXpress.com and Creative Commons imagies from Flickr.

As with many bloggers, we’ve been using royalty free images for many years. Many bloggers make use of images from Flickr and we have too but you can’t always find the right image there. I’ve even made a point to take more photos of people, places and things while traveling for later use in blog posts like the one to the right.

The stock photo site we’ve been using for several years recently decided to essentially double their prices (no matter how they spin it, that’s what they did) and it prompted me to ask the excellent people I’m connected with on Twitter for their suggestions on royalty free photography and image web sites. Here is a collection of 9 such sites that were suggested via Twitter or researched by TopRank. Which leads us to our poll for the most “blogger friendly” royalty free stock photo site:
